Abstract
The utility model relates to a liquid level automatic controller for submersible pumps. When people control the operation of the submersible pump, the idling operation of the water pump is frequently caused. The existing automatic control device causes the starting of water pump to be frequent, and increases the loss of the water pump. The interior of a sealing shell body is provided with a slide control rod which is acted by the water pressure and is driven by an elastic membrane cushion. The slide control rod is provided with a current conducting section. When the slide control rod slides, the current conducting section causes the current conducting contacts arranged on the side wall of the shell body to be mutually switched on, and the functions of the automatic starting and the stopping of the water pump are achieved. The utility model automatically controls the water level not to higher than some height, reduces the starting times of the water pump, and reduces the starting and stopping loss of the water pump.
Description
Liquid level automatic controller when the utility model belongs to the work of a kind of submersible pump.
Because submersible pump is to work under deep-well; often the down-hole liquid level is uncontrollable; unit in charge of construction's precipitation all is to adopt the method for manual observation drain opening water-outlet quantity to come the operation of control of pump for a long time; regular meeting causes water pump in down-hole no-load running like this; both strengthen power consumption, shortened the working life of water pump again.Also have the liquid level automatic control switch is set, this class switch is when water level one and surpasses a certain height point, submersible pump promptly starts work, when water level is lower than this height, promptly quit work, control automatically, because the water pump frequent starting at once though realized liquid level like this, both take electricity, increased the loss of water pump again.
The utility model aims to provide a kind of submersible pump liquid level automatic controller, and sort controller both can have been realized the automatic control to liquid level, can significantly reduce the frequent starting number of times of water pump again, thereby prolongs the submersible pump life-span.
For reaching above-mentioned purpose, the utility model adopts following structure: adorn the sliding controling rod 6 that an insulating material is made in housing 7 cavitys made from insulating material with being slidingly matched, housing 7 one ends are screwed with pressure adjustment screw 9, be provided with seal ring 10 between this screw and the housing, with this end sealing of housing, this screw inner end is stretched into aforementioned cavity and is joined by holddown spring 8 and aforementioned sliding controling rod 6 one ends, housing 7 the other ends are provided with sealing cover 1, establish an elastic membrane pad 3 between sealing cover and the housing, with this end sealing of housing, sealing cover is provided with the pressure port 2 that exposes the elastic membrane pad, the sliding controling rod termination directly or indirectly links to each other with elastic membrane pad 3, is embedded with power supply conductivity contact A and low water level control conductive contact H on the housing cavity sidewalls with drawing back certain distance
1, high water level control conductive contact H
2These three conductive contact inner ends and sliding controling rod 6 sliding contacts, terminal is drawn from housing sidewall respectively in its outer end, the position of drawing lead at housing seals with sealing material 11, the sliding controling rod made from insulating material be provided with when controlling rod when the pressure spring direction is moved, water level can be controlled contact H
1, H
2The conductive segment of connecting with power supply conductivity contact A 5 one in front and one in back.
The using method of this device is seen Fig. 1, Fig. 2, dotted portion M is aforesaid controller among Fig. 2, power supply conductivity contact A in control power supply one end a and the aforementioned controller is joined, will control power supply the other end b and A.C. contactor J coil one end joins, this coil the other end and its normally open contact J
KWith normally closed some J
bOne end joins, normally opened contact J
KThe other end and aforementioned energy are controlled conductive contact H with the low water level that power supply conductivity contact A connects earlier
1Join normally closed interlock J
bThe other end is controlled conductive contact H with the high water level that back and power supply conductivity contact are connected
2Join.Three normally open contact J with A.C. contactor J
K1, J
K2, J
K3Go here and there respectively in the three-phase circuit that submersible pump and power supply join.
The working principle of this device is: controller is placed a certain fixed position, down-hole, under the normal atmosphere state, the elastic membrane pad maintains an equal level, when the down-hole liquid level rises, the pressure that controller bears progressively increases, elastic membrane pad 3 promptly can push inward the sliding controling rod 6 that is pressed on the spring 8, when liquid level rises to certain altitude h
1The time, contact H
1At first connect with contact A, A.C. contactor this moment access failure also, the diving air pump inoperative is higher than h when liquid level is raised to
1A certain height h
2The time, make another high water level control contact H
2Connect normally-closed contact J with power supply conductivity contact A
bMake ac contactor coil connect power supply, submersible pump is started working, and liquid level descends, and sliding controling rod progressively resets, when conductive segment 5 makes contact H
2When breaking away from contact A, because normally opened contact is closed this moment, so coil continues the self-locking conducting, submersible pump works on, and reduces to h until liquid level
1, conductive segment 5 makes contact H
1When disconnecting with contact A, submersible pump quits work, and the down-hole liquid level is remained on be not higher than h
2The position.According to the situation that the controller placement location bears pressure, adjustable whole pressure adjustment screw 9 adapts to control liquid level height h
2Needs.
Use this controller can make submersible pump rise to certain height h at liquid level
2The time start submersible pump work, draw water makes liquid level be lower than this height the time not quit work at once, and can continue to draw water to liquid level for being lower than highly h of control
2Following h
1In time, just quit work, and the back liquid level that quits work rises to h
1During height, the diving air pump inoperative rises to h
2In time, just work, and so both can control automatically to guarantee that liquid level is not higher than setting height, can significantly reduce the number of starts of submersible pump again, can also prevent the water pump no load running.
